れらの吸収性物品への適用が提案されている。2. Description of the Related Art A water-absorbent resin has an absorption performance, a water retention capability,
Utilizing the gelling ability, absorbent articles such as disposable diapers, incontinence pads, sanitary napkins, breast milk pads, etc., pet sheets, pet floor sand, excrement disposal agents, waste blood gelling agents, drip absorbents It is used in various applications such as a freshness preservative. However, the conventional water-absorbent resin has excellent ability to absorb and retain urine, blood, body fluid, etc., but does not have an antibacterial function. Therefore, when absorbing urine, blood, body fluid, etc., there is a problem that organic substances are decomposed by fungi or microorganisms contained in the absorption liquid, and the decomposition products cause generation of bad odor, skin irritation, rash and the like. Furthermore, the absorbing gel is easily decomposed by fungi or microorganisms contained in the absorption liquid or bacteria in the air, and the malodor may be emitted due to the decomposition. From the above, from the viewpoint of hygiene and safety, the emergence of a material satisfying both the absorption function and the antibacterial function has been demanded. In particular, in absorbent articles such as adult paper diapers used for bedridden old people and sick people, the problems of bad odor and rash are serious, and a solution is desired. As a method of exhibiting an effect close to the above, a mixture of powders of a water-absorbent resin and zeolite (Japanese Patent Laid-Open No. Sho 5).
7-25813, JP-A-59-179114, JP-A-59-189854), and a composition in which activated carbon is coated with a water-absorbent resin (JP-A-56-314).

のできるものではなかった。However, these compositions have not always been able to obtain the effect of preventing the generation of bad odor and the effect of inhibiting spoilage, which are satisfactory for application to absorbent articles. That is, the mixture of the water-absorbent resin and zeolite,
Although the generated malodor can be absorbed, neither the water-absorbent resin nor the zeolite has an antibacterial function, thus suppressing the decomposition and decay of organic substances by microorganisms and fungi,
It is not possible to prevent the generation of this odorous product and the odor due to decomposition. Therefore, even when applied to an absorbent article, skin irritation, a rash, etc. could not be suppressed. In the case of a composition in which activated carbon is coated with a water absorbent resin or a composition comprising a water absorbent resin and a deodorant component extracted from theaceae plant, the deodorant component extracted from the activated carbon and the camellia plant has an antibacterial function. Since it is not shown, the same results as in the case of the above-mentioned zeolite are obtained, and it is not possible to suppress the decomposition and decay of organic substances by microorganisms and fungi. Although the water-absorbent resin composition containing benzalkonium chloride or a phosphate compound has some antibacterial action, it is not always satisfactory because the types of fungi and microorganisms to which it is applied are limited.

ができる。The antibacterial water absorbing composition of the present invention has the following features and effects. Not only an absorption function, but also an excellent antibacterial function is simultaneously expressed. The antibacterial component can suppress decomposition and decay of organic matter contained in urine, blood, body fluid, and the like absorbed by the water-absorbent resin by fungi, microorganisms, bacteria, and the like. As a result of suppression of decay, generation of offensive odor is small. Unlike the powder mixture of (A) and (B), separation of the two occurs due to vibration or impact, and when applied to the absorbent article, the water-absorbent resin and the antibacterial component are ubiquitous in the absorbent article. There is no need to worry. Since a composition having low dusting properties and excellent moisture blocking resistance is obtained, handling properties are good. It can be applied to an absorbent article by the same operation as a conventional water absorbent resin. By applying it to absorbent articles such as paper diapers and sanitary products, it is possible to impart an antibacterial function to the absorbent article and suppress the generation of foul odors, and reduce the occurrence of skin irritation and rashes. The performance is also good. The water-containing gel of (A) is kneaded with (B), dried and crushed. The aqueous liquid or dispersion of (B) is added to the powder of (A) and mixed to be carried without heating and drying. After mixing the powder of (A) and (B) in advance, a small amount of water is added to carry it without heating and drying, (B).
Can be produced by a simple operation such as adding (A) to the powder of (A), performing a mixing treatment, and then treating with a particulate inorganic substance.
